Specification of Letters Patent.

lPatented Uct. 14,1913.

Application led September 7, 1912. Serial No. 719,253.

-7 1o all 'whom it may confcrn Be it known that I, FRANK FoUn'r, a citi,- Zkn of the United States, residing at Fairfield, in the county of Je'erson and State of Iowa, have invented certain new and useful Improvements in Blow-Out Holders, of which the following is a specification.

This invention relates to blow-out holdersl for pneumatic tires .and has for its object the production of an efficient holder which may be readily secured around the inner tube of a tire and prevent its lbeing forced through any weak place or opening in the outer casing, by the air pressure from within.

Another object of this invention is the production of an efficient blow-out holder which may be so secured around the inner tube of the-tire to prevent the inner tube from becoming injured or wearing along the edge of the blowout holder.

With the above and other objects in view as will be hereinafter apparent the invention consists in general of certain novel concombinations and arrangements as will be hereinafter fully described, illustrated in the accompanying drawings, and speciieally claimed.

In the drawings :-Figure 1 is a bottom plan view of the bandage. Fig. 2 is a sec- 2-2, Fig. 1. Fig. 3 is a section taken on the line 3-3, Fig. 1. Fig. 4 is a transverse sectional view through the bandage showing the same in its stretched out condition. Fig. 5 is a transverse section through a tire showing the bandage positioned upon the inner tube. Fig. 6 is a fragmentary longitudinal section through a tire showing the manner in which the bandage fits upon the inner tube. Fig. 7 is a plan viel of the blank from which the bandage is made. Fig. 8 is a detail perspective of one end of the bandage.

By reference to the drawings, especially Fig. 7, it will be seen that the blow-out holder is formed from a blanksheet of fabric or other ldesirable material 1 and comprises a widened flap end portion 2, a central narrowed intermediate portion or portions 3, and an outer end portion 4, which outer end portion is slightly wider than the central portion or portions 3 and slightly narrower than the outer flap 2. Said portions 2, 3, and 4 vary in length, 2 being longer than 3 and 3 longer than 4.

After the blank is cut in the form as illustrated in Fig. 7 the end portion 4 is folded back upon the intermediate portion 3 and the two flaps 3 and 4 are then folded over upon the flap end 2, the end portion 4 being placed between the intermediate portion 3 and the flap end 2. These portions 2, 3, and 4 being folded as above described, the

blow-out holder is stitched longitudinally I thereof as indicated by the numeral 5, 1n Fig. 4. f

` A plurality of eyes (3 are formed adjacent the edges -of the blow-out holder through which eyes are adapted to pass the lacino 7 for firmly binding the blow-out holder around the inner tube as is illustrated in Fig. 5. A portion of the flap end 2 projects beyond one side of the blow-out holder thereby constituting a sealing iiap 8. This sealing flap is adapted to tit under the joint of the two sections of'the blow-out holder as illustrated by the numeral 9, in Fig. 3.

By having the different portions 2, 3 and 4 formed of different widths it will be seen that as the flaps are folded a tapering end will be formed upon each end of the blowout holder as indicated by the numeral 10, in Fig. 2. By having this structure it will be seen that no rib portions will be presented upon each end of the blow-out holder as is now usually the ease but the slightly tapering ends will gradually conform to the inner tube in such manner as to prevent injury to the inner tube and revent cutting thereof along the edge o the blow-out holder.

From the foregoing description it will beA ing of the blow-out holder upon the inner tube as to cause the tube to become worn or .inj ured.

What is claimed is :-y l A blow-out holder of th-e class described icc formed from a blank of material comprising a main flap, an intermediate narrower flap, and an outer ap wider than said 1ntermediate flap and narrower than said first mentioned Hap, said flaps being folded l together along the adjacent ends of said so a's to have said last-mentioned Hap fit between saidrintermediate flap and said first-mentioned flap, said first-mentioned flap extending beyond the edge of the other flaps and'eonstituting a sealing Cap for said blow-` outholder as the samevts around the inner tube of a tire, the side edges of said flaps after the same have been folded being` pro- 10 vided with eyelets, said flaps being stitched blow-out holder, and lacing means passing through said eyelets-for seeuring the blowout holder around the inner tube of a tire.
